Hello Jennifer
I always wash my fabrics, FQ, metres of etc. The one exception is Jelly Rolls I read somewhere not to wash these. Anyhow I wash all my fabrics by hand in my sink & then rinse by hand until the dye runs clear. I then put the fabric into my washing machine in a Mesh Bag & put through a rinse cycle along with fabric conditioner.
I then tend to just press them straight from the machine & trim any straggly frayed edges & lay them on my airer to give them a final air.
Hope this helps.
